Writing unicode ncurses applications for busybox
Hi all, I write ncurses based application which utilizes russian characters. It looks like this: wchar_t *unicode_string = L"Это юникод"; mvwprintw(stdscr,1,5,"%ls", unicode_string); And it works pretty well on my desktop. I enabled all UNCIODE_ config options I found I enabled terminal: export TERM="linux2.2" I copied terminfo into my busybox system (kernel 3.2) When I run my application, only ascii is printed. Unicode chars are absent: no garbage or whatever. How it can be workarounded if it is possible. Application is dynamically linked and all libraries were transferred too ___ busybox mailing list busybox@busybox.net http://lists.busybox.net/mailman/listinfo/busybox
Re: Writing unicode ncurses applications for busybox
I tested with export ru_RU.UTF-8 This was set in init script I created file with russian chars in it and it also displayed as but it seems to be ls-related. I saw uch an issues in mailing list In my case it is not displayed at all On 18.11.2014 13:25, Richard Moore wrote: Hi, You need to set LANG, and it needs to be set in the controlling terminal, e.g. export LANG=en_US.UTF-8 Cheers Rich On 18/11/14 09:47, Pugnator wrote: Hi all, I write ncurses based application which utilizes russian characters.

Re: Writing unicode ncurses applications for busybox
It didn't do the trick fr some reason.. here is my config: CONFIG_UNICODE_SUPPORT=y # CONFIG_UNICODE_USING_LOCALE is not set # CONFIG_FEATURE_CHECK_UNICODE_IN_ENV is not set CONFIG_UNICODE_COMBINING_WCHARS=y CONFIG_UNICODE_WIDE_WCHARS=y # CONFIG_UNICODE_BIDI_SUPPORT is not set # CONFIG_UNICODE_NEUTRAL_TABLE is not set CONFIG_UNICODE_PRESERVE_BROKEN=y I also tested with CONFIG_UNICODE_USING_LOCALE enabled with the same result. Can it be because of bad terminal set in TERM envvar? Only linux2.2 make TUI looks as it designed.

I suspect either your libc (uclibc?) was built without locale/UTF-8 support, or your ncurses was built without wide character support. If you're using Buildroot or a similar tool, it should offer you the option to configure these aspects of the build.

Re: Writing unicode ncurses applications for busybox
Thank you a lot for your help. After stracing on different machines, I found the problem - lack of fonts So the correct chain to make busybox support specific language with ncurses: ash.c patch you provided correct terminfo database (linux works fine for me) correct font, for example Lat15-Fixed16.psf or cyr-sun16.psfu etc On 18.11.2014 16:31, Richard Moore wrote: Hi, Sorry then I don't know the answer - I spent a long time getting UTF to work. This was my writeup , maybe you can find something useful in it. http://www.richud.com/wiki/WHDD_Live_ISO_Boot_CD (Note that setting the LANG in rcS only works when WHDD fires up, if WHDD is exited and then restarted UTF support won't work as the variable is then no longer set in that terminal.)
